cleanup | simple command line utility that organises files | Command Line Interface library

I want to run cleanup code after a certain block of code completes, regardless of exceptions. This is not a closeable resource and I cannot use try-with-resources (or Kotlin's use). In Java, I could do the following:

I have a requirement to build a SSIS package that sends HTML formatted emails and then saves the emails as tiff files. I have created a script task that processes the necessary records and then coverts the HTML code to the tiff. I have split the process into separate packages, the email send works fine the converting HTML to tiff is causing the issue.

When running the package manually it will process all files without any issues. my test currently is about 315 files this needs to be able to process at least 1,000 when finished with the ability to send up to 10,000 at one time. The problem is when I set the package to execute using SQL Server Agent it stops at 207 files. The package is deployed to SQL Server 2019 in the SSIS Catalog

What I have tried so far

I started with the script being placed in a SSIS package and deployed to the server and calling the package from a step (works 99.999999% of the time with all packages) tried both 32 and 64 bit runtime. Never any error messages just Unexpected Termination when looking at the execution reports. When clicking in the catalog and executing package it will process all the files. The SQL Server Agent is using a proxy and I also created another proxy account with my admin credentials to test for any issues with the account.

Created another package to call the package and used the Execute Package Task to call the first package, same result 207 files. Changed the execute Process task to an Execute SQL Task and tried the script that is created to manually start a package in the catalog 207 files. Tried executing the script from the command line both through the other SSIS package and the SQL Server Agent directly same results 207 files. If I try any of those methods directly outside SQL Server Agent the process runs no issues.

I converted the script task to a console application and it works processing all the files. When calling the executable file from any method from the SQL Server Agent it once again stops at the 207 files.

I have consulted with the companies DBA and Systems teams and they have not found anything that could be causing this error. There seems to be some type of limit that no matter the method of execution SQL Server Agent will not allow. I have mentioned looking at third-party applications but have been told no.

I have included the code below that I have been able to piece together. I am a SQL developer so C# is outside my knowledge base. Is there a way to optimize the code so it only uses one thread or does a cleanup between each letter. There may be a need for this to create over ten thousand letters at certain times.

Update

I have replaced the code with the new updated code. The email and image creation are all included as this is what the final product must do. When sending the emails there is a primary and secondary email address and depending on what email address is used it will change what the body of the email contains. When looking at the code there is a section of try catch that sends to primary when indicated to and if that fails it send to secondary instead. I am guessing there is a much cleaner way of doing that section but this is my first program as I work in SQL for everything else.

Thank You for all the suggestions and help.

Updated Code

I've wondered this for a while and the necessity of checking whether pointers are valid or not in my own library is even necessary. Should I just expect the user to pass in the correct pointers because it's their job if they're using the library?

For example if I have a library which allocates and returns a structure

Im doing a Carrousel that when it opens a "news" you can see a description in a modal, that works perfect, but when you click on a offer you redirect to another page with the info about that product.

It's working but when you do it, in the consolo shows the error of memory leak "react-dom.development.js:67 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function."

I'm knew using useEffect and I don't know how to avoid this.

Thanks for your time

I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

This image is taken from PDF File that is being generated as result (and it is zoomed out at 55%)

I want to make this look better. Something similar to this, if I may

This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

Edit: Using the code provided by onkar ruikar, I was able to achieve very good results. However, it created the same problem that I was facing previously. The question was asked here: Horizontally merge and divide cells in an HTML Table for Timetable based on the Data in Python File

I changed up the template.html file of mine and then ran the same code. But I got this result,

As you can see, that there were more than one lectures in the First Slot of Monday, and due to that, it overlapped both the courses. It is not reading the

The modified template.html file has this code,

What is considered best practice for aborting on errors in C?

In our code base we currently have a pattern using

In a module, I have two tests:

I've started using docker buildx to tag and push mutli-platform images to ECR. However, ECR appears to apply the tag to the parent manifest, and leaves each related manifest as untagged. ECR does appear to prevent deletion of the child manifests, but it makes managing cleanup of orphaned untagged images complicated.

Is there a way to tag these child manifests in some way?

For example, consider this push:

I often see the following code which is the first view looks good since one is used to check a precondition before doing something else.

But when one reads the name of the method it feels like the preceding if statement already is included in the method itself. So is there any reason to write the code like it is in this example or could one just skip the if-statement and run ThrowIfCancellationRequested directly.

Of course its a different thing if one need to cleanup before exiting then I fully understand the use of the if-statement.
